This application is a divisional application of prior application Ser. No. 16/766,489, filed on May 22, 2020, which is a U.S. National Stage application under 35 U.S.C. § 371 of an International application number PCT/KR2019/001959, filed on Feb. 19, 2019, which is based on and claims priority of a Korean patent application number 10-2018-0020317, filed on Feb. 21, 2018, in the Korean Intellectual Property Office, the disclosure of which is incorporated by reference herein in its entirety.
TECHNICAL FIELDEmbodiments disclosed in the disclosure relate to an apparatus and method for supporting a plurality of subscriber identification modules (SIMs) in a wireless communication system.
BACKGROUND ARTTo improve sound quality and efficiency of a voice call over a circuit switched (CS) network, a voice over internet protocol (VoIP) technology based on an internet protocol (IP) has been widely used. Unlike a CS mode, voices may be exchanged through data packets in the VoIP technology. The VoIP technology is applicable to various network platforms based on a packet data network. For example, for VoIP in long term evolution (LTE) wireless communication, voice over LTE (VoLTE) may be used.
An electronic device supporting a voice call function may include an identification module to provide a user with various services such as user authentication, billing, and a security function. The identification module may include, for example, a subscriber identification module (SIM). The electronic device may include a single SIM or may include a plurality of SIMs such as a dual SIM.
DISCLOSURE Technical ProblemWhen an electronic device supports a dual SIM, for example, a first SIM may support a CS mode and a second SIM may support a VoIP technology. For another example, both the first SIM and the second SIM may support the VoIP technology. A technology where both the first SIM and the second SIM use VoLTE may be referred to as dual VoLTE. In the dual VoLTE technology, the first SIM and the second SIM may use the same radio frequency (RF) resource.
Because an RF resource is used during a voice call using the first SIM when the electronic device supports the dual SIM and the dual VoLTE, although another electronic device requests a voice call using the second SIM, there may be a problem in which it is impossible for the electronic device to receive a request message.
In various embodiments of the disclosure, as an electronic device transmits information associated with a SIM which is in use by the electronic device to another electronic device, the other electronic device may request a voice call through the SIM which is in use by the electronic device among a plurality of SIMs.
In various embodiments of the disclosure, as the information associated with the SIM includes data indicating whether to release a phone number corresponding to the SIM, the electronic device may fail to provide another user with the phone number for the SIM when a user does not want to release the phone number.

According to an embodiment, the electronic device 101 may receive a packet-based VoIP service such as VoLTE using the first SIM 201 or the second SIM 202. For example, when network operators of the first SIM 201 and the second SIM 202 differ from each other, the electronic device 101 may perform a voice call through the first network 205 and the first server 280 when using the first SIM 201 and may perform a voice call through the second network 207 and the second server 290 when using the second SIM 202.
According to an embodiment, the electronic device 101 may include a processor 220 (e.g., a processor 120 of
According to an embodiment, the electronic device 101 may include the memory 230 (e.g., a memory 130 of
According to an embodiment, the first server 280 or the second server 290 may provide the electronic device 101 with an IMS service (e.g., VoIP). In the disclosure, the first server 280 and the second server 290 may be referred to as IMS servers. The first server 280 or the second server 290 may be a single entity and may be a set of a plurality of entities. The first server 280 or the second server 290 and the electronic device 101 may transmit and receive a session initiation protocol (SIP) message for a voice call.
According to an embodiment, a network (e.g., the first network 205 or the second network 207) may refer to an architecture which transmits data between the electronic device 101 and the first server 280 or the second server 290. For example, the network may include a base station (e.g., an evolved node b (eNB)) and an evolved packet core (EPC), which are defined by the LTE specification. The EPC may include, for example, a mobility management entity (MME), a serving-gateway (S-GW), a packet data network (PDN)-gateway (P-GW), a policy charging and rules function (PCRF), and a home subscriber service (HSS). The base station 210 may be connected with the electronic device 101 over a radio channel and may play a similar role to an existing radio network controller/base station controller (RNC/BSC). The MME may be a node for controlling a control plane of the EPC and may perform various functions such as the connection and release of the radio bearer. The S-GW may be a node for controlling a user plane for an LTE radio access network (RAN) in the EPC, which may operate as a mobility anchor for the electronic device 101 or may generate or remove a data bearer under control of the MME. The P-GW may be a node for connecting an external network (e.g., the Internet, the first server 280, or the second server 290) with the EPC, which may allocate an IP address to the electronic device 101 and may apply a quality of service (QoS) according to the PCRF. The PCRF may be a device for controlling a policy associated with a quality of service (QoS) of a user, which may deliver a policy and charging control (PCC) rule corresponding to the policy to the P-GW. The HSS may be a node having subscriber information.
According to an embodiment, in the network, the QoS may be applied for each evolved packet system (EPS) bearer. One EPS bearer may be used to transmit IP flows having the same QoS requirements. According to an embodiment, the electronic device 101 may transmit voice data to the first serve 280 or the second server 290 over the S-GW and the P-GW using a dedicated EPS bearer. Similarly, the electronic device 101 may receive voice data from the first server 280 or the second server 290 using the dedicated EPS bearer.
According to an embodiment, the electronic device 101 may be registered with the first server 280 or the second server 290 over the network (e.g., the first network 205 or the second network 207). The registration may mean that, for example, a packet data network (PDN) between the electronic device 101 and the first server 280 or the second server 290 is established by the P-GW. The electronic device 101 may initiate the procedure of registration with the first server 280 or the second server 290 in booting instance or may initiate the procedure of registration when a network environment of the electronic device 101 is changed. The first server 280 or the second server 290 may identify whether it is possible for the electronic device 101 to perform VoIP, based on whether the electronic device 101 is registered.
In embodiments described below, it may be assumed that the electronic device 101 performs a packet-based voice call (e.g., VoLTE) in the above-mentioned LTE communication system. However, embodiments below are not limited to the LTE communication system and are applicable to a 3GPP 5th generation (5G) communication system or another packet-based wireless communication network.

According to an embodiment, the framework layer 320 may perform data processing for delivering data for the IMS service or the internet service to the modem 330. The framework layer 320 may include a telephony 322, a radio interface layer (RIL) 324, and an IMS 326.
According to an embodiment, the telephony 322 may provide an application programming interface (API) for accessing (e.g., transmitting and receiving data) the modem 330 via the RIL 324 at the application layer 310. The telephony 322 may include, for example, a call origination/termination service, a data service, a SIM recognition service, an SMS, a network search and connection service, or the like. The API provided by the telephony 322 may vary with a type (e.g., GSM, CDMA, or IMS) of network to which data is transmitted via the modem 330.
According to an embodiment, the RIL 324 may provide an interface associated with wireless communication between the program 140 and the modem 330. For example, applications included in the application layer 310 may control the modem 330 through the RIL 324 using the API provided from the telephony 322 and may transmit and receive a message with the modem 330.
According to an embodiment, the IMS 326 may process data associated with an IMS service. For example, when a call application is executed in the electronic device 101 and when the electronic device 101 receives a user input requesting a voice call from another electronic device from the user, the IMS 326 may generate a message (e.g., an SIP INVITE message) requesting the voice call and may deliver the generated message to the model 330 via the RIL 324. For another example, when a message requesting the voice call from the electronic device 101 is received via the modem 330 from the other electronic device, the IMS 326 may deliver the received message to the application layer 310 to notify the user of the electronic device 101 that the call request is received.
According to an embodiment, the IMS 326 may store the information associated with the contact of the other electronic device or the information associated with the SIM. The information stored by the IMS 326 may be the same as the information stored by the application layer 310, or at least a portion of the information may be stored in another format. According to an embodiment, the information associated with the SIM may be stored in a mapping table format.
According to an embodiment, the modem 330 may process a transmitted and received message in a baseband. The modem 330 may transmit the data processed in the baseband to the first server 280 or the second server 290 via a communication module 203 of

The information associated with the SIM may include, for example, information associated with the first SIM 201 or information associated with the second SIM 202. According to an embodiment, the first electronic device 401 may adaptively transmit the information associated with the second SIM 202 based on whether the second electronic device 403 is IMS registered. For example, when the second electronic device 403 is IMS registered, the first electronic device 401 may transmit the information associated with the second SIM 202 to the second electronic device 403 using an SIP message. For another example, when the second electronic device 404 is not IMS registered, the first electronic device 401 may transmit the information associated with the second SIM 202 using a hypertext transfer protocol (HTTP) or a short message service (SMS).
According to an embodiment, the first electronic device 401 may identify whether the second electronic device 403 is IMS registered, via the IMS server 402. For example, the first electronic device 401 may receive a message, indicating whether other electronic devices registered with a contact of the first electronic device 401 are IMS registered, periodically per specified time from the IMS server 402. For another example, when an IMS registration state of the second electronic device 403 is changed, the first electronic device 401 may receive a message indicating whether the second electronic device 403 is IMS registered from the IMS server 402.
According to an embodiment, in operation 415, the second electronic device 403 may receive a user input requesting a voice call for the first SIM 201. For example, the second electronic device 403 may receive a user input selecting a contact of the first electronic device 401 (e.g., a user name of the first electronic device 401) in a contact list stored in the second electronic device 403. For another example, the second electronic device 403 may receive a user input inputting a phone number (e.g., 010-1234-xxxx) corresponding to the first SIM 201 of the first electronic device 401.
According to an embodiment, in operation 420, the second electronic device 403 may transmit a message requesting a voice call for the second SIM 202 to the IMS server 402. The request message may include, for example, an SIP INVITE message.
According to an embodiment, in operation 425, the IMS server 402 may transmit a message (e.g., an SIP INVITE message) requesting a voice call to the first electronic device 401. According to an embodiment, while the first electronic device 401 performs a voice call with another electronic device rather than the second electronic device 403 using the second SIM 405, the IMS server 402 may notify the first electronic device 401 that the second electronic device 403 requests the voice call by transmitting a paging signal.
According to various embodiments, although the first electronic device 401 changes the SIM, when the second electronic device 403 knows information associated with the changed SIM (e.g., the second SIM 202) in advance, it may request a voice call through the changed SIM. Thus, although the first electronic device 401 is performing a voice call according to VoIP through the changed SIM, the first electronic device 401 may notify a user that the second electronic device 403 requests the voice call by receiving a message requesting the voice call from the IMS server 402.
